Hagenau is currently a German town, but is in the Alsace region of what was Northeast France at the time this coin was stuck. It was founded by the Holy Roman Emperor Frederick I Barbarossa in AD 1154, who on the site of a hunting lodge build a fortress with an Imperial palace to house part of the crown Jewels of Charlemane.

Denomination : Silver Pfennig (or denier). Mint : Hagenau.

Date : struck ca. AD 1190 to 1200, and is either a coin struck by Frederick I Barbarossa who dies in AD 1190, or relatively soon after his death.

Size : 16.9 x 17.6 mm. Weight : 0.65 grams.

Reference : Nessel 86 variety.

Grade : gVF with attractive old collection toning and exceptionally well struck for this normally very crudely struck series.

Obverse : This is probably a view of the Imperial palace, with a cross on top.

Reverse : Knight on horseback (possibly Frederick I Barbarossa).

It is not 100% clear which side of this coin is the obverse, and which is the reverse, and one can see coins of this city where sometimes the palace is listed as the obverse, and other times it is listed as the reverse.
